Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf (pz*H = pyrazole, pzH; 3,5-dimethylpyrazole, dmpzH; indazole, indzH; 3-(2-pyridyl)pyrazole, pypzH) were obtained from fac[ReBr(CO)(3)(pypzH)] by halide abstraction with AgOTf and subsequent addition of the corresponding pyrazole. Successive deprotonation with Na2CO3 and NaOH gave neutral fac[Re(CO)(3)(pz*H)(pypz)] and anionic Na{fac-[Re(CO)(3)(pz*)(pypz)]} complexes, respectively. Cationic fac-[Re(CO)(3)(pz*H)(pypzH)]OTf, neutral complexes fac-[Re(CO)(3)(pz*H)(pypz)], and fac-[Re(CO)(3)(pypz)(2)Na] were subjected to photophysical and electrochemical studies. They exhibit phosphorescent decays from a prevalently (MLCT)-M-3 excited state with quantum yields (F) in the range between 0.03 and 0.58 and long lifetimes (tau from 220 to 869 ns). The electrochemical behavior in Ar atmosphere of cationic and neutral complexes indicates that the oxidation processes assigned to Re-I -> Re-II occurs at lower potentials for the neutral complex compared to cationic complex. The reduction processes occur at the ligands and do not depend on the charge of the complexes. The electrochemical behavior in CO2 saturated media is consistent with CO2 electrocatalyzed reduction, where the values of the catalytic activity [i(cat)(CO2)/i(cat)(Ar)] ranged from 2.7 to 11.5 (compared to 8.1 for fac-[Re(CO)(3)Cl(bipy)] studied as a reference). Controlled potential electrolysis for the pyrazole cationic (3a) and neutral (4a) complexes after 1 h affords CO in faraday yields of 61 and 89%, respectively. These values are higher for indazole complexes and may be related to the acidity of the coordinated pyrazole.

Structural modulation of transition metal carboxylates has been studied by employing different auxiliary ligands in the reactions of metal acetates with substituted benzoic acids. A series of neutral transition metal benzoates [Cu(tbba)(2)(imH)(2)] (1), [Cu(tipba)(2)(2,4,6-collidine)(2)] (2), [Co(tbba)(2) (dmpH)(2)] (3), [Co(tipba)(2)(imH)(2)] (4), [M (tmba)(2)(pymeH)(2)] (M = Cu (5), Co (6) and Zn (7)), [Zn(tmba)(2)(pydmeH(2))] (8), [Cu-2(tmba)(2)(pydmeH(2))(2)] [(tmba)(2)(tmbaH)(2)] (9) and [Zn-2(dmp)(2) (tbba)(2)(dmpH)(2)] (10) have been isolated as products from the reaction between the respective metal acetates and substituted benzoic acids (acids used: 4-tert-butylbenzoic acid (tbbaH), 2,4,6-triisopropylbenzoic acid (tipbaH), 2,4,6-trimethylbenzoic acid (tmbaH)) and N-donor auxiliary ligands (imidazole (imH), 3,5-dimethylpyrazole (dmpH), 2,4,6-collidine, 2-pyridinemethanol (pymeH), and pyridine-2,6-dimethanol (pydmeH(2))). The new complexes have been characterized by both analytical and spectroscopic methods. The molecular structures of 1-10 have further been established by single crystal X-ray diffraction studies. The complexes 1-8 are mononuclear, while compounds 9 and 10 have been found to be dinuclear due to the role of benzoic acid in 9 and pyrazolate anion as bridging ligand in 10. The geometry around the metal ion is square-planar in 1 and 2, tetrahedral in 3, 4 and 10, octahedral in 5-7 and 9 and trigonal-bipyramidal in 8. Complexes with ligands that contain additional functional groups such as > NH and -OH are involved in hydrogen bonding interactions. These weak interactions lead to the formation of 1-D linear polymers or 2-D sheets.

Comparison of various organic compounds such as glycols, amines and alkanolamines as organocatalysts in amidation of fatty acid methyl esters with 3-(dimethylamino)-1-propylamine was made for the first time. It was experimentally detected that catalysts containing OH-groups (alcohols, glycols, glycerol and aminoalcohols) influence the reaction rate. Moreover, catalytic effect is depending on the catalysts geometry significantly. 1,5-diols (e. g. diethylene glycol and diethanolamine) were found to accelerate the reaction more than other OH-groups containing additives. It was supposed, that this catalytic effect is caused by specific associative interactions between reactants and 1,5-diols, what was confirmed by quantum mechanics calculations. Catalysts concentration effects on the reaction rate were also investigated.

A berberine 9-O-pyrazole alkyl derivative, a chemical compound (called B3) previously synthesized by our group, shows anti-cancer activity. However, B3 lacks targeting cytotoxicity to cancer cells, leading to obvious toxic side effects on normal cells. To solve this problem, here, we prepared a drug delivery system, namely, AS1411-GO/B3 for tumor targeting, in which nano-graphene oxide (GO) sheets were employed as the drug carrier, and the aptamer AS1411 was conjugated onto GO for tumor targeting. GO also had a photothermal effect, which helped the release of B3 from GO as well as the thermal cytotoxicity to cells. We found that the release of B3 could respond to acid conditions, indicating that the tumor intracellular environment could promote the release of B3, thus allowing it to perform chemotherapy effects. This system could also release B3 in response to photothermal heating, moreover, combined photothermal therapy and chemotherapy to improve the anticancer activity was achieved. This AS1411-GO/B3 platform with chemo-photothermal synergetic therapy provides a very promising treatment for tumors.

Two penta-coordinate complexes of the general formula [Co(L-n)(NCS)]ClO4, where L-1= {bis[(3,5-dimethyl-1H-pyrazol-1-yl)ethyl]-[(3,4-dimethoxypyridin-2-yl)methyl]}amine and L-2= {bis[(3,5-dimethyl-1H-pyrazol-1-yl)ethyl]-[(4-methoxy-3,5-dimethylpyridin-2-yl)methyl]}amine, have been synthesized and thoroughly characterized. Each of the cobalt(ii) atoms is penta-coordinated in the {CoN5} donor set with a distorted square-pyramidal geometry in [Co(L-1)(NCS)]ClO4 center dot MeOH (1), while the vicinity of the central atom can be described as a distorted trigonal-bipyramidal geometry in [Co(L-2)(NCS)]ClO4(2) as revealed using the SHAPE analysis. Differences in interatomic parameters among the cobalt(ii) and donor atoms in 1 and 2 have definite impact on the magnetic features of both compounds. The complexes show an easy-axis magnetic anisotropy (D = -38.5 cm(-1) for 1 and D= -8.5 for 2), and both complexes reveal a large rhombicity with E/D = 0.21 for 1 and E/D = 0.29 for 2. The ZFS parameters (g, D and E) were also calculated using CASSCF/NEVPT2 methods and they are in good agreement with those determined from experimental data. A frequency dependent out-of-phase susceptibility has been observed in external magnetic field (B-dc= 0.1 T) revealing the following parameters of slow relaxation of magnetization for 1: energy of the spin reversal barrier, U-eff = 16.0 cm(-1)(U-eff/kB = 23.0 K) and the relaxation time, tau(0)= 1.28 x 10(-6)s. In the case of complex 2, no maxima of frequency dependent out-of-phase susceptibility have been observed and thus, the value of U-eff= 17 cm(-1) has been estimated using the expression U-eff = vertical bar D vertical bar x (S-2- 1/4). It has been demonstrated that the degree of substitution and the type of substituents on the pyridyl moieties of the tripodal ligands (L-1 and L-2) used in these penta-coordinate cobalt(ii) complexes have significant impact on structural and magnetic features.

Purpose: Patients with inoperable pancreatic adenocarcinoma have limited options, with traditional chemoradiation providing modest clinical benefit and an otherwise poor prognosis. Stereotactic body radiation therapy for pancreatic cancer is limited by proximity to organs-at-risk (OAR). However, stereotactic magnetic resonance-guided adaptive radiation therapy (SMART) has shown promise in delivering ablative doses safely. We sought to demonstrate the benefits of SMART using a 5-fraction approach with daily on-table adaptation. Methods and Materials: Patients with locally advanced, nonmetastatic pancreatic adenocarcinoma were treated with 50 Gy in 5 fractions (biologically effective dose(10) 100 Gy) with a prescribed goal of 95% planning target volume coverage by 95% of prescription, prioritizing hard OAR constraints. Daily online adaptation was performed using magnetic resonance-guidance and on-table reoptimization. Patient outcomes, treatment factors, and daily adaptation were evaluated. Results: Forty-four patients were treated with SMART at our institution from 2014 to 2019. Median follow-up from date of diagnosis was 16 months (range, 6.7-51.6). Late toxicity was limited to 2 (4.6%) grade 3 (gastrointestinal ulcers) and 3 (6.8%) grade 2 toxicities (duodenal perforation, antral ulcer, and gastric bleed). Tumor abutted OARs in 35 patients (79.5%) and tumor invaded OARs in 5 patients (11.1%). Reoptimization was performed for 93% of all fractions. Median overall survival was 15.7 months (95% confidence interval, 10.2-21.2), while 1-year and 2-year overall survival rates were 68.2% and 37.9%, respectively. One-year local control was 84.3%. Conclusions: This is the first reported experience using 50 Gy in 5 fractions for inoperable pancreatic cancer. SMART allows this ablative dose with promising outcomes while minimizing toxicity. Additional prospective trials evaluating efficacy and safety are warranted. (C) 2020 The Author(s). Published by Elsevier Inc. on behalf of American Society for Radiation Oncology.

Four new coordination compounds of nickel (II) with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine were synthesized; their composition and structure were confirmed with IR-spectroscopy and elemental analysis. The structures of products 13 and 15 were unambiguously established in an X-ray diffraction study. Compounds 13 and 15 crystallize in the orthorhombic space groups Pna2(1) and P2(1)2(1)2(1) correspondingly and represent a monomeric octahedral nickel complexes, that are typical for tridentate scorpion-type ligands. New method for immobilization of nickel complexes with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine on silica gel modified with aminopropyl groups was proposed. The EXAFS/XANES analysis indicated that Ni atom in the supported complexes adopt almost octahedral geometry, being partly surrounded by nitrogen atoms from organic ligand and partly grafted to silica surface through silanol groups, with Br- in outer coordination sphere. Both the original and the supported complexes, when activated with Et2AlCl or Et3Al2Cl3, catalyze ethylene oligomerization with the predominant formation of butene isomers. Generally, the immobilized complexes show higher activity and better selectivity towards 1-butene formation.
